AudiogoN Forums: Suggestions for DAC isolation?

Suggestions for DAC isolation?

My DACs transformer hums/buzzes slightly and I would like to control some of the associated vibration. The DAC is relatively light weight (not in sound). Contacted the manufacturer who said it's normal.

It currently resides on a 3" thick maple slab with 2 VPI bricks on top. Large Audio Points brass cones under maple slab. Thinking about Still Points, Finite Elemente, Black Diamond type units between the maple and DAC.

Maybe something like the Finite Elemente Resonator/The Sound of Silence on top.

1. Has anyone had similar problems?
2. Any suggestions for controlling vibration under DAC?
3. Mass loading or vibration dissipation better on top?

Thanks for any insights you can offer.

Very interesting Richard_stacy, thanks.
It is a Berkeley Alpha DAC. Any other users?

I like the sound quality of this DAC, one of the best I've heard, so no plans to get rid of it.
